Morse Code

In a recent post, {Missee Lee (was 15lb Pike caught in Martham)), Ed mentioned tapping in Morse Code. I have never been happy with the concept of reliably sending Morse Code by tapping, as a dash (dah) is three times as long as a dot (dit). Tapping just produces a transient sound not a sustained sound. So "M" (- -) would sound very similar to "EE" (. .) et cetera (just for a bit of Latin too!).
